By popular demand, we've gathered together and summarised all of the information we can find on high-filtration masks and their respective certificates. In the following guide, we will explain in short the features of KN95, FFP2 and N95 masks, so you understand that the differences between them when you come to make your buy.
N95 masks, KN95 and FFP2 face masks: let's get things straight
As well as the classic blue surgical masks, which can be perfectly fine for avoiding infecting others, but less useful for protecting your self, you can even purchase certified filtering face masks. The initials FFP in the name FFP2 stand for'Filtering Face Piece', and these masks provide quite effective filtration of harmful microparticles, which is why they're used in environments which pose a higher risk of contagion.
When you begin looking for filtering masks that have passed scientific tests to verify their protective characteristics, you soon encounter initials like FFP2, KN95 and N95, especially if you're looking for something to guard you from pollutants or microparticles that carry viruses. The certification of those masks varies depending on their place of origin.
Filtration functionality of KN95, N95 and FFP2 masks
The KN95, N95 and FFP2 masks provide similar levels of filtration: all three have a filtration capacity over 94%, according to the standards that govern their technical features.
- FFP2 face masks: 94% filtration capacity
- N95 face masks: 95% filtration capability
- KN95 face masks: 95% filtration capability
The standards governing KN95, N95 and FFP2 masks
KN95, N95 and FFP2 masks differ from the process used to calculate their filtration. This process changes according to where they're produced, since it follows the certification rules established by the nation where the apparatus' operation is tested.
We've put together a short review of the differences between the criteria adopted to certify KN95, N95 and FFP2 masks.
Although their overall aim is the same -- to reevaluate the apparatus' actual capability to protect individuals from inhaling potentially damaging substances or particles -- each of the three standards that certify filtering face masks differs from others. The differences lie in the processes adopted to check the apparatus -- based on the sort of test completed, the requirements and test conditions may therefore vary.
FFP2 mask lasting
FFP2 masks could be marked with the letter (R) to get'reusable' or (NR) for'non-reusable'. Most FFP2 masks fall into the latter category -- they're protective devices that progressively become less effective with the passing of time. Because of this, an FFP2 mask typically lasts approximately eight hours at at-risk surroundings, or a single work shift. Even if it's worn while keeping a safe distance in low-risk locations, the mask must nevertheless be thrown away after eight hourssince breathing and exposure to moisture slowly impact its filtration capability and physical integrity. Once they become significantly damp, FFP2 masks must be binned.
